IG_REC_error_desc_len

Returns a size of buffer for the error description.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_REC_error_desc_len_get( enumIGRecError nErrCode, LPAT_INT lpDescSize );

Arguments:

Name	Type	Description
nErrCode	enumIGRecError	Code of the recognition engine error.
lpDescSize	LPAT_INT	Pointer to the variable to receive the buffer size.

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

This function does not process image pixels.

Example:

	Copy Code
AT_ERRCOUNT ErrCount = 0; AT_ERRCODE ErrCode = IGE_SUCCESS; AT_INT ExtErrCode = 0; AT_INT iBufSize = 0; AT_CHAR* lpszBuffer = NULL; //... IG_err_record_get(0, NULL, 0, NULL, &ErrCode, 0, &ExtErrCode, NULL, NULL, 0); ErrCount += IG_REC_error_desc_len_get((enumIGRecError)ExtErrCode, &iBufSize); lpszBuffer = (AT_CHAR*) malloc(iBufSize); if(lpszBuffer) { ErrCount += IG_REC_error_desc_get((enumIGRecError)ExtErrCode, lpszBuffer, iBufSize); free(lpszBuffer); }

Copy Code

AT_ERRCOUNT ErrCount = 0;
AT_ERRCODE ErrCode = IGE_SUCCESS;
AT_INT ExtErrCode = 0;
AT_INT iBufSize = 0;
AT_CHAR* lpszBuffer = NULL;

//...

IG_err_record_get(0, NULL, 0, NULL, &ErrCode, 0, &ExtErrCode, NULL, NULL, 0);

ErrCount += IG_REC_error_desc_len_get((enumIGRecError)ExtErrCode, &iBufSize);

lpszBuffer = (AT_CHAR*) malloc(iBufSize);
if(lpszBuffer)
{
    ErrCount += IG_REC_error_desc_get((enumIGRecError)ExtErrCode, lpszBuffer, iBufSize);
    free(lpszBuffer);
